PENNSYLVANIA, A COR- SHEET-METAL ARTCLE.

Application filed February '7, 1920. Serial No. 357,002.

To all 'whom it may concern Be it known that 1, ALEXANDER ALLowAY,

a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Sheet-Metal Articles, of

which the following is a specication.

This invention relates to structural features of sheet metal articles and as eX- emplied are applied to a waste basket.

The invention involves a corner construction in which a corner rib is secured to the sides of a corner and by means of the fold the fastening devices are covered. 1t also involves a construction of thetop of the article, a construction of the bottoni of the legs, and a construction for securing the bottom in the receptacle. Other details will appear from the specification and claims.

The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a side elevation of the basket.

Fig. 2 a section of a vfragment of the sides and bottom with the joint in the process of formation.

Fig. 3 a fragment of a. side and bottom showing the completed joint.

Fig. A a section on the lines 1w-4 in Figs. 1 and 5.

Fig. 5 a side elevation of a leg bottom.

Fig. 6 a section on the line 6-6 in Fig. 1.

Fig. 7 a structure showing a corner rib in process of construction.

Fig. 8 shows a form of side blank.

Fig. 9 a corner construction of the top bead.

1 marks the side, 2 the bottom of the basket, 3 the top bead, Lt a corner rib terminating in legs, and 5 a leg bottom. The 40 sides are united by a folded joint, one side having a return bend 7 and an adjacent side having an inward bend 6 extending along the return bend and a back'fold 8 arranged within the return bend.

The bottom is secured to the sides in the manner shown in Figs. 2 and 3. The sides have a return bend9 and an inward bend 10. The bottom has a return bend 11 which is hooked into the loop formed by the return bend 9. 1t will be noted that this forms a positive lock preventing the lifting of the bottom or the disengagement of the sides.

rlhe blank of the side has a slight projection 12 at its upper end formed by a notch 13 and the edge portion 14: is turned to form a connection through the bends 6, 7 and 8. the upper edge of the side is turned over a core 15 forming a bead. The folds forming the bead have their corner or abutting edges brought into contact at 16. This is made possible particularly by the shape of the material as shown in Fig. 8 and by a stretching process after the fold is formed, that is to say, after the fold is formed the metal is forced up to the corner bringing the edges 16 into intimate contact thus making a inish.

Corner ribs are provided for the basket. These make a finish at the corner and stiften the receptacle as a whole, improve its appearance and by extending them they form legs for the basket. The corner strip 18 has a securing edge 19 from which extends a return fold 19a terminating in a bend or turn 22, the return bend contacting the face of the side. A securing strip 1n is fastened to the basket sides at each side of the corner preferably by spot welding and the edges of this securing strip are provided with a return bend 1b. In assembling the parts the return bend 1b is not entirely closed as shown in Fig. 7. The corner strip with the securing edges 19 are placed against the return bends 1b and the corner of the basket is placed on a horn 20 and a die 21 crushes down the corner strip closing the return bend 1b on the securing edge 19 and closing the bend 22 giving it a completed shape as shown in Fig. `6. Vith a return fold covering the edge portion 19 and the outer bend 22 forming a finish along the edge of the rib, the outer bend or turn 22 should be beyond the edge of the part 19 and is slightly bent inwardly into contact with the side.

In order to nish the bottom of the legs so that they will not mar the floor or catch in rugs it is desirable to provide a larger surface than is presented by the bare end of the sheet metal. provide, therefore, the

bottom pieces E23 which are in the form of an angle and have a bead formed over a bent wire 24, the bead being formed by a fold 25. The return plates of the metal after being folded over the core 24C are brought together at 26 and inserted within the bend 22. In forming the rib, it will be understood that the portion below the sides not having the backing that the sides aiford does not close this space formed by the bend 22 so that this angle piece may be readily inserted.

What I claim as new is 1. An article of manufacture having a corner formed of sheet metal; and a corner rib having its edges secured to the sides of the corner and extending outwardly from the corner and having folds extending outwardly over the portion secured to the sides.
